Application filed. August 2. 1907. Serial No. 386,689.

To all whom it may concern:

Be it known that I, ALBERT Larsen, a citizen of the United States,-residing in Peekskill, in the county of VVestchester and State of NewYork, have invented certain new and useful ln'iprovernents in Machinesfor Making Embossed Wall-Paper, of which the following is aspecification.

T his invention relates to an. improved machine for making wail-pa erthat is embossed on the front and smoot. on the back, and in which thespaces between the embossed sheet and rear-layer are either unfilled orfilled with a suitable cement, and for this purpose the inventionconsists of a machine for making embossed wall-paper which comprises apaper-roll, an embossing-roll engraved with the design to be produced,said embossing-roll rotating in contact with the paper-roll, a heatedpresser-roll rotating/in contact with the embossing-roll and ser ving tounite the face and rear-layers of per, and supply-rolls for the face andrearayers.

The invention consists further in a machine for making embossedwall-paper which comprises an embossing-roll, i PIJflPGP-IOll rotatingin contact therewith, a heated presserroll,'rotating-in contact with theembossingroll and means-for supplying a suitable cement by which thespaces between the embossed face-layer and the smooth rear-layer arefilled up. V.

In the accompanying drawings, Figure 1 represents a side-elevation of myimproved machine for making embossed. wall-paper,

Fig. 2 is a vertical longitudinal section of the machme shown in Fig. 1,Fig. 3 1s a vertical longitudinal section of a modified construction ofmachine, and Figs. 4 and 5 are vertical transverse sections through theembossed wal1- 'aper made by my improved machine, one fieing Without anyfilling between the front and rear-layers and the other with a suitablecement filling between the same.

Similar letters of reference indicate corrcspending parts throughout theseveral figures of the drawings.

Referring to the drawings, a a represent the side-standards of myimproved machine- The sidefor making embossed wall-paper.

-standards are connected by transverse braces and provided with bracketsa at their lower leftand right-hand sides and another bracket 0, attheir upper right-hand side. On one side-brackets], is supported thesupply-roll r for the facepaper, while on the other side-bracket a issupported the shaft of the guide-roll r by which the finished wallpaperis conducted off. On the upper right hind-bracket a" are arranged thejournalbearings for the shaft of a heated presser-roll e. in the upperportions of the side-standards a a are arranged journal-bearings d, thelower stationary. journal-bearings b sup porting the shaft of a rotarypaper-roll b, and the upper adjustable bearings d the shaft of anembossing-mild. Helical springs (Pare interposed between thejournal-bearings for, The em.

The design is em- Power is transbeing then conducted off by theguide-rollr to a conveyer-belt r and then wound up into a roll. T herear-layer is coated with an adl'iesive layer on its upper slde, so thatit W111 adhere to the embossed front layer by the 'n'essure of theheated roll'against the eml ossing-roll. The roll e is heated at theinterior by gas, steam, or otherwise.- The pressure of theembossing-roll and heatedroll on the embossed face-layer and the coatedrearlayer unites the two layers and forms the ernbossed wallpaper.

The mm of the w ell-paper can be finished in paper, silk, oil cloth orother fabric, while the rear-layer remains smooth. The noneinbossedports of the lace-layer are united with the reenleyer by the pressurebetwcci. tho einbhssing and heated rolls.

As the face-pnpcr istightly hugged by the pressurooi" the embossingo'oil on the impcrq'oll,it one hossed and sinnllteneously tied toward the embossing-roll andheated roll which latter is perfectly smooth I When it is desired tofili the spaces between the embossed face-layer and the rcardeyer, ehopper g is arranged between the em--' bossing-roll and hee-tcdwoll towhich it suit able cement is supplied by means of scoops or shovels,said cement foeing preferably composed of wood-iibers mixed withoxidized linseed oil, resin, etc The cement is sup plied in the form ofa thick paste, which is made plastic by the heat of the presscr roll e.I The cement fills the cavities bet-weer'i the embossed face and resrleycrs and forms thereby a soiid-rclief Wall-paper which resembles tlieWell known lincrpste wall-paper and has the strong, solid emldumhleproperties of the same. This embossed pa" or can never lose its shapeand is capable o" reslst- 111g considerable pressure, while thcemhossedpaper which is not iilled up with cement in cavities is less capable ofresisting pressure; both papers, however, are produced with the requireddesign at a considerable speed and with e superior finish, according, tothe quality and style of the well-paper to be produced.-

Figs. 4 and 5 show respectively transverse sections of the unfilled andfilled well-papers.

The advantages of my embossing machine are that a solid-relief embossedwall-paper v The sdhc sivc employed for the rear-layer is preferably ithrough between the claim as new and desire to secure by Letters Patent:
